Coaster

The bumps in this ride are perfect. Not sure whether they are on purpose or not but if they are - good - if they are not you're lucky at having them at the right places. The onride POV felt extremely like a classic what the track-shaping is concerned. As long as you don't carry the bumps over to B&Ms or over manufacturers than Arrow and old Vekomas I can see a ton of potential. Huge plus point for these bumps xD
Besides, there are unfortunately quite a few things wrong with this coaster. The cross-tie spacing is really unreasonable and bad looking, that probably is because of the radical change between low and high stress. While Arrow sometimes does change the spacing, they only do it rather subtly so I'd probably only touch the low stress, normal stress, and high stress. Also, keep in mind that high cross-tie density is used in the section with great forces and low ones in sections with less. That means that especially in the valleys and corkscrews you should use normal or even high stress rather than low stress.
The supports are not very likable as well. The loop and corkscrew supports are too thin and the normal supports are placed too far apart from each other. For these mistakes, I highly recommend looking at real images of Arrows while building them in NL to get a more realistic result.

Scenery/Theming

I really liked the use of terrain textures - you kinda seem to know where rock and where grass has to go. Other than that the scenery is extremely simple but not necessarily something any coaster needs. So I guess what you created did the job.

Overall an average coaster. There are still really obvious mistakes but I can't deny how realistic the track shaping felt in the onride POV even if the loops are too big for an Arrow which genuinely builds small and forceful loops.
